    Environmental checklist: Seattle-Tacoma International Airport (SEA) Widen Arrivals Drive

    The Port of Seattle filed an environmental checklist in May 2021 for a project to widen Arrivals Drive at Seattle-Tacoma International Airport (SEA) from two lanes to four lanes, aiming to reduce congestion and improve safety for passengers and ground transportation vehicles. Construction was planned to begin in mid-2023 and last approximately 18 months, involving road realignments, updated stormwater drainage, new LED lighting, and utility relocations. The project was designed as a standalone improvement but coordinated with broader airport master plan efforts to accommodate potential future infrastructure expansions at SEA.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
